Hello, I am currently working with Hashtable which is loaded by default in the Moose image. With the latest image, I tried to do: (HashTable new at: #a put:1;yourself) inspect. And I got an inspector with the red square of death... It seems that the visualization wants to get the item at the position 1 in the Hashtable but it cannot succeed because there is no item at 1 (obviously, it is an hashtable). Can someone with GtTools knowledge take a look at that? Thanks in advance, Cheers, Vincent !!!************************************************************************************* "Ce message et les pi?ces jointes sont confidentiels et r?serv?s ? l'usage exclusif de ses destinataires.

RTForceBasedLayout without overlapping arbitrary shapes

by Cris Fuhrman

Hello, Here's an example code using RTForceBasedLayout (from an example on this list a while back): ------------ view := RTView new. objects := RTObject withAllSubclasses. elements := (RTBox new size: #numberOfMethods; color: (Color blue alpha: 0.5)) elementsOn: objects. elements @ RTPopup new. view addAll: elements. RTForceBasedLayout on: elements. view @ RTDraggableView . view open ------------ It produces: [image: Inline image 1] Is it possible to have the RTForceBasedLayout such that the result has no overlapping boxes (or rectangles)? I realize setting force: to some large negative number will help, but it's not ideal because it creates a lot of empty space. In d3 (with SVG) there are a couple of examples of what I'd like to achieve (although they don't show edges): https://bl.ocks.org/mbostock/1062383 (arbitrary shapes) https://bl.ocks.org/mbostock/3231298 (arbitrary circles that stick to each other) The animation isn't important in my case. I wasn't sure where/how to apply the transform operation after a layout has been done in RTForceBasedLayout. Any hints? Here's what my graph looks like: [image: Inline image 2] The code I have to produce this is too much to post, so I used the example at the top. My code also uses RTForceBasedLayout new charge: -1000; on: b elements. Cheers!

Roassal: Locate a legend text below a line

by Hernán Morales Durand

Hi everybody, I have this complicated code to draw a line with separators at both ends, I try to put the legend text with #below but nothing is changed : | view e1 e2 l1 label | view := RTView new. label := RTLabeled new color: Color black; below; text: 'Class IIa'; yourself. e1 := RTBox new element color: Color black; height: 10; width: 1; yourself. e2 := RTBox new element color: Color black; height: 10; width: 1; yourself. l1 := RTStyledMultiLine new color: Color black; solidLine; edgeFrom: e1 to: e2. view addAll: (Array with: e1 with: e2 with: l1). l1 @ label. RTHorizontalLineLayout new on: view elements. view elements pairsDo: [ :a :b | b translateBy: 100 @ 0 ]. ^ view Any suggestion? Hernán

Re: software reingineering guidelines

by abdelghani ALIDRA

Hi, Thank you Nicolas and Anne for the hints/links @Alex Yes, genetic algorithms are “abstract” algorithms. I am actually talking about analysing the code of the frameworks for developing different genetic algorithms to solve all kinds of optimisation problems (knapsack, Traveling Salesman Problem but also “real life" problems : image processing, and many artificial intelligence problems) There are many GA frameworks. Some popular ones are : ECJ (https://cs.gmu.edu/~eclab/projects/ecj/), OpenBeagle (http://vision.gel.ulaval.ca/~parizeau/Publications/beagle-gecco.pdf), WatchMaker (http://watchmaker.uncommons.org/), HeuristicLab (http://dev.heuristiclab.com/)… Abdelghani Message: 4 Date: Thu, 16 Feb 2017 11:02:44 -0300 From: Alexandre Bergel <alexandre.bergel(a)me.com> To: Moose-related development <moose-dev(a)list.inf.unibe.ch> Subject: [Moose-dev] Re: software reingineering guidelines Message-ID: <9D54173C-8CD7-4873-A5F9-AC0EF570EAB2(a)me.com> Content-Type: text/plain; charset=utf-8 Ah ah! Sorry, I read too fast! But it is not clear what are you referring to when you mention “generic algorithm”? Can you give an example? Alexandre

Hi guys, I downloaded Moose from http://moosetechnology.org/res/download/moose_suite_6_0-linux.zip My system info: $ uname -a Linux mvs-virtual-machine 3.19.0-69-generic #77~14.04.1-Ubuntu SMP Tue Aug 30 01:29:21 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux $ lsb_release -a No LSB modules are available.

Roassal: Why the grey outline?

by Hernán Morales Durand

The attached capture is the one implemented by the method #exampledoubleCurves. If you zoom the image you will notice the grey edge of each green and blue line. The same happens in #exampleVerticalAndHorizontalLines Is there a way to remove it the grey around each line? Cheers, Hernán

AthensCairoCanvas>>setPaint: receiving a "Color transparent"

by Hernán Morales Durand

I am using stable branch of Roassal2 in Pharo 5 and Win 8.1 to draw a figure for a paper (but the problem is the same loading the latest versions SmalltalkHub). When trying to open a grapher, I get a yellow-cross red morph window inside #setPaint: . The transparent color passed as argument came from AthensCairoSurface>>clear The same figure used to open without problems some months ago. All the Roassal examples open without problems. That's why here is the link to the fuel out stack with the halt previous to the crash : https://dl.dropboxusercontent.com/u/103833630/Debugger-Stack-AthensCairoCan… Is this a well-known bug? Any suggestion? Cheers, Hernán

Re: software reingineering guidelines

Hi Alex, The idea is not to use genetic algorithms to improve software quality. Rather, to use Moose to enhance the design of existing frameworks for genetic algorithms. I have attached a brief description of the project to this email. It is in french but this is not a problem for you I think :) > On 15 Feb 2017, at 12:00, moose-dev-request(a)list.inf.unibe.ch wrote: > > Message: 2 > Date: Tue, 14 Feb 2017 08:13:22 -0300 > From: Alexandre Bergel <alexandre.bergel(a)me.com <mailto:alexandre.bergel@me.com>> > To: Moose-related development <moose-dev(a)list.inf.unibe.ch <mailto:moose-dev@list.inf.unibe.ch>> > Subject: [Moose-dev] Re: software reingineering guidelines > Message-ID: <6DD0680F-39CB-4E2D-8E42-9ECFF1D77542(a)me.com <mailto:6DD0680F-39CB-4E2D-8E42-9ECFF1D77542@me.com>> > Content-Type: text/plain; charset=utf-8 > > hi Abdelghani, > > How do you plan to use genetic algorithms ?

Book, Working Effectively with Legacy Code

by Ben Coman

Interesting to see this is the top mentioned book on stackoverflow. I wonder if Moose can facilitate any of its contained topics and maybe leverage its popularity. </randomThoughForTheDay> cheers -ben
